WINDOW-SCREEN.

SPECIFICATION forming part of Lettersv Patent No. 562,095, dated June16, 1896.

Application filed January 17, 1895. Serial No. 535,206. (No model.)

To @ZZ whom t may concern:

Be it known thatl, WINFIELD B. PHILLIPS, a citizen of the United States,residing at Fenton, county of Genesee, State of Michigan, have inventeda certain new and useful Improvementin Tindow-Screens; and I declare thefollowing to be a full, clear, and eXact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,which form a part of this specification.

My invention pertains to an improved window-screen, having for itsobject a screen of simple,economical, and durable construction, and ofsuperior eiiiciency and beauty.

My invention consistsof the construction and arrangement hereinafterdescribed and claimed, and illustrated in the accompanying drawings, inwhich Figure l is a view in perspective. Fig. 2 is a cross-section onthe line 2 2, Fig. l. Fig. is a detail view showing one of the groovedbars of the frame with a portion of the screen fabric or wire nettingengaged therewith. Fig. 4 is a detail view of one of the tenoned bars ofthe frame with a portion of the wirenetting engaged therewith. Fig. 5 isan enlarged cross-section on theline 5 5, Fig. l. Fig. Gis a detail viewmore fully illustrating the engagement of the said clips with the twoframes.

My invention more especially has in view an adjustable screen-frame soconstructed as to be readily operated and adjusted without liability ofbinding and of such strength that center bars obstructing the view maybe omitted.

I carry out my invention as follows: The screen as a whole isconstructed of two screenframes A and A', each of said frames having oneend bar A2 and one upper and lower bar A3 and A3. With each frame is awire-netting C, engaged with the three bars thereof. The upper and lowerbars of one of said frames are each provided with a rectangular groovea, extending from end to end thereof, as indicated in Fig. 3. The upperand lower bars of the corresponding frame are provided with rectangulartenons a', extending the whole length of each of said bars, as shown inFig. 4. The tenons of the upper and lower 4 dicated at b.

vbars of one of the frames slide in the grooves v j ustment of the twoframes, the one relative to the other.

It will be seen. that the adjacent faces of the bars A3 A3 of the twoframes are parallel the one to the other on each side of the grooved andtenoned engagement of the one with the other, said bars beingconstructed with perpendicular parallel faces a3 a4, extending outwardfrom the groove andtenon, with perpendicular parallel faces c5 a,extending' inward from the groove and tenon to the rabbeted portions ofthe adjacent bars, so that the two bars of the frame A A have theiradjacent faces parallel throughout in their contact the one with theother.

The two frames are held adjacent the one to the other'by clips B B,secured to the frames, the frames being movable through said clips,respectively, to permit the adjustment of the frames, as may be desired.

vThe clips B are preferably constructed with flanges b b at theiryopposite edges to project over the face of the two frames, as indicatedin the drawings. The clips may each be nailed at one end to one of theframes, asin- The inner edge of each of the bars of each frame israbbeted, as shown at CL2, to receive the corresponding edge of thewire-netting and allow suflicient play for the proper adj ustability ofthe two frames. The wire-nettin g engaged with each frame has its freeedge bound within a folded strip of metal C. This binding dispenses withthe necessity of a crossstrip engaged with the frame toward the innerends of the upper and lower pieces thereof, as has been commonheretofore.

I prefer to manufacture both of the tenoned bars in one of the frameswith a groove IDO similar to the groove d in Fig. 3, and then to insertand secure in place a tenon-strip into the groove, inasmuch as in thismanner all the bars of the frame can be made on the same machine withthe same knives. In this manner, primarily, all the bars designed forthe upper and lower bars of each frame are duplicates the one of theother. The tenoned strips are then secured in that portion of the barsrequired to be provided therewith. While this is a simple and desirablemanner of constructing the tenoned bars, I would, however, have itunderstood that I do not limit myself solely thereto, as the tenonedbars may be constructed in any suitable manner with the rectangulartenons eX- tending from end to end thereof.

Atenon or tongue of rectangular shape in cross-section extending fromend to end of the bar to fit into a correspondingly-shaped groove in acorresponding bar is believed to be novel and especially in combinationwith the clips B B. It is obvious that the two frames A A with theirtongues and tenons so constructed would not hold together without theclips or some analogous device for holding the parts together, as therewould be nothing to preventlateral displacement. The u se of the clipsin combination with the tongueand grooved bars, constructed as abovedescribed, provides a windowscreen that is strong and one which will notbind in adjustment thereof. Such a construction, moreover, enables thebars of the screen-frame to be made thinner than in other adjustablescreens,while at the same time the two frames A A may be adjusted widerapart than has been the case with other frames, thus securing additionaladvantages, while at the same time the screen as a whole is of tastefulappearance, especially since I am enabled, as above set forth, todispense with any cross pieces or bars at the free edges of thewirenetting.

It is well known that screen-frames made adj ustable by dovetailedtongues and grooves without the clips B B are weak and are very liableto bind and to be pulled apart. So, too, clips without the bars beingtongued and tenoned, as embodied in my invention, are liable to grindinto the bars and permit the two adjustable frames to be separated.

In my improved screen the use of clips is to hold the two frames A Afrom lateral disengagement, while the tongues and grooves maderectangular in cross-section aiord the easiest and strongest adjustmentpossible and the easiest manner of adjusting the frames, as the framesare not dovetailed and the tongues and grooves do not have to performthe oiiice of holding the two frames together; the tongues and groovessimply serving for the ready adjustment of the two frames. Moreover, the

strength secured in a screen so constructed tirely dispensed with. Themetal edge C on the wire fabric is only for the stiffening of thenetting and not to add strength to the frames.

I prefer to nail one of the clips B I3 to one of the frames, the otherclip being nailed to the opposite frame. The clips are also preferablyso located as to form a stop to prevent pulling the frames apart.

As shown in Fig. I, it will be evident that when the frame A is pulledto the right, for example, the clip secured thereto will move to theright therewith. So, also, when the frame A is moved tothe left thecorresponding clip moves therewith. This will cause the two clips tostrike against one another when the frames are adjusted outward to theirfull capacity and stop their being pulled apart.

What I claim as my invention is- A window-screen having three-sidedframes, A,A,laterally adjustable the one with respect to the other, eachof said frames constructed with a vertical end bar A2, and with upperand lower horizontal bars A3 A3 rabbeted on their adjacent faces attheir inner edges, combined with a screen fabric engaging with therabbeted edges of each frame, and provided with a binding of sheet metalat its inner edges; the upper and lower bars A3 of one of said framesbeing constructed with straight sides, U-shaped grooves in one of thevertical faces thereof and extending continuously from end to end ofsaid bars, the upper and lower bars A3 of the other frame constructedwith correspondingly-shaped tenons ou the vertical faces thereofadjacent to said grooves extending continuously from end to end of saidbars and having movable engagement in the grooves of the correspondingframe, the upper and lower faces of said grooves and tenons beinghorizontal and parallel throughout, the adjacent grooved and tenonedbars A3 being provided with perpendicular parallel faces CL3 ai,extending from the groove and tenen respectively outward to the outeredge of the bars and with perpendicular parallel faces c, a, extendingfrom the groove and tenen respectivelyV inward to the rabbeted portionof the bars; and clips secured to the upper and lower bars of one ofsaid frames engaging the corresponding upper and lower bars of theopposite frame to hold the two frames together and to permit of theirlateral adjustment, substantially as set forth.

In testimony whereof I sign this specification in the presence of twowitnesses.
